2003 Chevrolet Trailblazer transmission problems

Filed Jan 12, 2022 · Transmission · PA

While driving my Trailblazer in A4WD on slippery road conditions, I went to pulled out of a parking lot and there was a loud sound like my whole front end fell out and the front end completely locked up. Almost causing an accident. I had to dial back to 2HI quickly to unlock to front end. There was no light indicating any problems. Been driving it 2HI since with out any problems. Still no service light or anything, but feels like I'm stuck in A4WD. Feels like there is a drag and a pulling to the right. Also using more gas since. It was a scary, afraid to try the 4x4 functions again. Another snow storm is on the way!

Tl* the contact owns a 2003 chevrolet trailblazer. While driving various speeds, the front end of the vehicle vibrated. The vibration was more pronounced while the engine was idling. Also, while ascending up a hill, the vehicle would not properly accelerate. The vehicle was taken to an independent mechanic who was unable to determine the cause of the failures. The mechanic replaced the motor mounts, control arms, and tension belt; however, the failures continued. The manufacturer and an unknown dealer were notified of the failures. The failure mileage was 177,000. The VIN was invalid.

I've had to replace the transmission twice now I have in fact reported to gm asking if there was any recourse I may take and they simply flat out told me no! So I started hearing a noise and then the transmission started to not shift properly to the point you could not drive it. To me this I consider this a very unsafe condition because if it stopped moving altogether I'd be on the highway with the possibility of an accident occurring. I do have an invoice but no scanner, it did cost me 3k or better on both occasions to replace it. I'd like to know if there's anything I'm able to do to be reimbursed for any or all of the inconvenience I've concurred.

As I accelerated from a stopped position the vehicle became undrivable. The transmission had to be completely rebuilt. Planetary failed as well as other broken parts. I still have the receipt from cottman's transmission for $3k. The transmission was warrantied for 3 yr. It has been 5, and the transmission has again failed. Planetary again broken. Vehicle now has 150,000 mi. I think it is absurd that there has been nothing done by the federal safety agency. No recalls, cost assistance, or even an investigation. Considering the number of complaints, action should have been taken long ago. Even gm admits problems in some of it's bulletins. Why are you doing nothing about this.

Put vehicle in park and stayed in drive. Shut vehicle off and put on park however still in drive and now will not start. Since I work on vehicles I looked at transmission linkage and found cable came off transmission linkage. Plastic clip broken. Looked on line and found transmission shifter cable repair clip for $14.99. Since it was special order I went to dealer and was told there is no repair kit and that they have plenty of shifter cables in stock $75.00 went ahead and ordered aftermarket part special order 2 days and today 3 days later was told out of stock and none available til december. Coincidence or is this a common problem? I'm afraid someone will not know or realize vehicle still in drive when shifter moves to park and not moving shifter linkage at transmission.

I was driving in the left lane on interstate highway 290 (youngman highway) at about 65 m.p.h. When smoke began wafting from the area where the steering column meets the dashboard. I took immediate evasive action, pulled onto and off the shoulder onto the grass, shut the engine off, ran to the barrier fence and watched to see if vehicle was going to burst into flames. After calling aaa, about ten minutes had elapsed without further smoke so I assumed I could drive to the next exit ramp at colvin blvd. (about 1,000 feet away) and off to a wendy's parking lot where I waited for a aaa flatbed truck. My SUV was flatbed towed to my dealership, fuccillo chevrolet on grand island, where the problem was diagnosed as a faulty ignition switch, code number c0379. Total cost of repair was$222.66. It would be nice to be reimbursed for this expense. Though no visible fire was observed, the smoke was a clear sign of problem that was so hot it caused oxidation of material into visible smoke.
